| 摘 要： | The catalytic hydrogenation ofp-nitrophenol to p-aminophenol was investigated over Ni/TiO2 catalysts prepared by a liquid-phase chemical reduction method. The catalysts were characterized by inductively coupled plasma （ICP）, X-ray powder diffraction （XRD）, transmission electron microscopy （TEM）, X-ray photoelectron spectra （XPS） and temperature-programmed reduction （TPR）. Results show that the titania structure has favorable influence on physio-chemical and catalytic properties of Ni/TiO2 catalysts. Compared to commercial Raney nickel, the catalytic activity of Ni/TiO2 catalyst is much superior, irrespective of the titania structure. The catalytic activity of anatase titania supported nickel catalyst Ni/TiO2（A） is higher than that of rutile titania supported nickel catalyst Ni/TiO2（R）, possibly because the reduction of nickel oxide to metallic nickel for Ni/TiO2（A） is easier than that for Ni/TiO2（R） at similar reaction conditions.
